DP-12 Shotgun
The DP-12 has two 7-round magazine tubes and two barrels! It’s a double-barrel pump gun.

I saw a prototype of a third next-gen pump at the NRA Show, but, honestly, didn’t pay that much attention to it. I did think it odd that the shotgun, the DP-12, was coming from Connecticut Shotgun Manufacturing Co., CSMC, (doing business as Standard Manufacturing LLC), the foremost manufacturer of premium double-barreled shotguns in America. CSMC got its start making Winchester Custom Shop Model 21s, the iconic American side-by-side double. From that it’s expanded to multiple lines of high-end doubles, including its top-of-the-line A. H. Fox guns that rival its much older Italian and English competitors. Using modern manufacturing techniques combined with old fashion hand-work craftsmanship, CSMC has brought high-end classic shotguns into reach for a much wider audience.

CSMC seemed to me to be an unlikely company to step into the “black bullpup shotgun” market. We were already headed to CSMC for the shotguns and to feature another eclectic product, the 3/4 scale .22 LR “Tommy Gun” I’d also seen at the NRA show… a friend of mine asked me to take a close look at the DP-12 while I was there.

The two other entries in the field, the KSG and the UTS-15, both take a similar path—a single barrel fed by two separate 7-round tubes, the Kel-Tec tubes on the bottom of the barrel; the UTS-15 tubes on top. The UTS-15 has user-selectable tubes, while the KSG has to be manually shifted to the second tube when the first is empty. A lot of my concerns focused on those systems that shifted from tube to tube. I really liked the SRM semi-auto system with its manually operated rotary tubes (didn’t like the high MSRP’s, however).

The DP-12 goes down a completely different, and decidedly unconventional, path. It has two 7-round tubes, but it also has two barrels! That’s right… a double-barrel pump gun. Two rounds are chambered with each pump; the trigger is then pulled two times, the first to fire the right barrel, the second to fire the left barrel. Pump, and you’ve got two more rounds.

Essentially, CSMC made the decision to combine two time-proven systems—the pump shotgun, which we’ve had down since the 1890s, and the single-trigger double-barrel shotgun, which is easily as old. CSMC is building some of the best double-barrel shotguns in the world. They understand shotgun triggers on a DNA level. The two separate pumps are likewise conventional; think two Remington 870s bolted together.

Okay, that’s different!

CSMC approached the design with the same manufacturing philosophy it uses for all its shotguns—start with a big honking piece of metal and work from there. CSMC already manufactures its own barrels, drilled, not hammer-forged, on steel bars, using custom drill bits designed to minimize chatter and deliver a smoother bore. The receiver for the DP-12 is machined from a solid block of aluminum. Overall, the gun is built like a tank.

When I first handled the double-barrel pump, the pump system felt like an 870, a real gun rather than a tactical Super Soaker. It looks clunky, but the bullpup doesn’t feel clunky when shouldered. In fact, it feels like nothing so much as an FNH FS-2000 bullpup carbine, which I have a lot of rounds through. It’s got rails in the appropriate places, an AR standard safety, threaded barrels for chokes or breachers, and it loads like those two 870s bolted together.

The trigger is fine — probably shouldn’t be surprised at that considering CSMC’s core competence. My question was how was I going to adapt to pull-pull-pump. Keep in mind that I shoot a double barrel in cowboy competition and have literally thousands of rounds through my Browning BSS in the course of a year. I also compete in 3-Gun Heavy Metal, which requires a 12-gauge pump. For that I shoot a Benelli Nova, which handles a lot clunkier than the DP-12, by the way.

I got a chance to run two 16-round load sets through the gun: one high-brass field loads; one heavier self-defense loads. Here are my initial impressions:

The pull-pull-pump proved to be a non-issue. It took about six rounds to dial it in. The caveat is that I would need a lot more rounds in a training/competition-pressure environment to see how the DP-12 truly performs.

There is simply no faster follow-up shot than just pulling the trigger. That’s why dangerous-game hunters use double rifles. Even a semi-auto action has to cycle for the next shot. On the pull-pull, I ran the gun the same way I run a double in competition, firing the second shot the instant the trigger resets.

The pump is short and precise, easy to run. The forearm has a raised area on the front to keep the pump hand from sliding forward. The test gun I shot had a vertical foregrip attached.

The bullpup configuration, an excellent recoil pad, and the weight of the gun (I’m guessing around 8 pounds) made recoil a non-issue. To me, the gun balances extremely well (again, think FS-2000). It’s fat, but you don’t notice when it’s on the shoulder.

The bullpup configuration makes the shotgun extremely maneuverable, much more so than a standard-length gun. I have worked shoot-houses with 870s, ARs, and other rifles, and the bullpup really comes into its own in a confined space.DP-12 Shotgun Flyer

Conclusions? I really think the DP-12 has a lot of potential, enough that I’ve asked for a Testing and Evaluation gun to give it a full workout and film it for Down Range TV. I might not want to carry this gun to Afghanistan, but it would be one heck of a bedroom gun with tube No. 1 loaded with Hornady Tap buckshot and tube No. 2 loaded with Federal law-enforcement slugs. I’m thinking in that situation, I win. It also has huge potential as a car gun and for other close-quarters situations. The DP-12 is based on proven technology, and there’s no strange Rube Goldberg engineering to sneak up and bite the user on the butt.

The questions I have are on topping up the mag, reloading, and, in general, the entire manual of arms, but I think those are solvable with a few hands-on days to work out the techniques. Bullpups require a different manual of arms from other guns we’re familiar with. I’m going through that with the Tavor; it’s not bad, it’s just different.

I know how the DP-12 is made because I walked through the entire process, and the quality is really impressive. That’s important to me, and it should be important to you.

My understanding is (as seen in the flyer above) is that the DP-12 will be exclusively distributed by Cheaper Than Dirt!, and the MSRP will be in the $1k region, although that is not fixed at this point. I don’t have an ETA on the sale of the DP-12, but I do know for a fact that it is currently in full production.

I say no.
One of things I like most about the UTAS & KSG systems is that you can switch between loads & fire several of one load if need be. Say you need to breech with a couple of slugs & then switch to buckshot, you fire a couple of rounds out of one tube & then switch to the other.
As I understand this article, you essentially have a double barreled shotgun with a 14 round tube & you're committed to what is loaded. Unless you wanna work with a sidesaddle or bandoleer in which case, just get an 870 bullpup kit or 590 Mossy & save a few $$$.

I googled the KSG incident and IF it is the same one that you are talking about, I would say that the fault was in the vertical grip, not the shotgun. That's not to say some improvement could be made to the KSG to prevent such things from happening but it's about like blaming your tires for your brakes failing.

Again, that is IF it is the same incident. And of course, pending the unprinted information...
